Functions of the DHW circuit
generated prematurely if the remaining time until the disinfection temperature is reached is
shorter than the adjusted 'Duration'. The indication is automatically reset when the disinfec-
tion temperature is properly reached during the following thermal disinfection cycle.
Thermal disinfection for preventing legionella infection causes:
− Excessively high return flow temperatures during the disinfection cycle (return flow tem-
perature limitation suspended)
− Excessively high DHW temperatures after thermal disinfection has been concluded
− Possibly lime scale, which can have a negative effect on heat exchanger performance.
This function is not available when a storage tank thermostat is used.
